I just replaced my sump pump. I put in a 1/3 HP Coleman (little giant) 50gpm @ 5' w/ 1/2" solids ok, replacing a functional 9 yr old hydromatic with a diaphragm switch. (9 years of use seemed to be pressing my luck ... mostly spring and summer rains)
The existing pvc line had an in line check valve. I left it in place so that when the new pump is replaced someday, it would be less messy when removed.
I also used a screw in check valve. I did this because I had one laying around, I didn't have a pvc connector for the pump, and it made the pvc connection to the pump very easy.
I chose not to use the pvc pipe from the old pump. I wanted to keep the old pump assembly together in case the new pump failed prematurely. I wanted a quick, drop in replacement to be available.
Thus, I have 2 check valves on 1 pump. It tested ok and was very quiet. Unusual, yes. But it makes sense given the description above.
Can I anticipate a problem from having 2 check valves on 1 line?
Also, is this new pump any good? It boasts lifetime warranty. How long can the old hydromatic sit on a shelf before it goes bad?
